I like some of these ideas, particularly the flexible system of delegation. But right now the issue-ranking system seems like a weak link. It's too simplistic and could easily devolve into an exercise in voting on bumper-sticker slogans. There should be tools for more reasoned exploration of the issues, like an argument mapping tool for instance (http://en.wikipedia.org/wiki/Argument_map). Don't just let me vote on a tweet-sized solution, let me see the arguments made for and against it in a structured way that I can also vote on.
